IC 1848, Inside the Soul Nebula

Inside the core of the Heart Nebula. The scale is fairly big, and I think it's fun to click the full res image and then mouse-zoom in (especially the right side of the field) to see the structures of the hydrogen gas up close.

This data I took last October, but never got around to processing it. But after watching Adam Block's tutorial on the PixInsight script LocalFuzzyHistographHyberbolization (say that five times fast!), I used this object as my first try. The contrast boost is very impressive. I haven't yet succeeded with the technique of using a blend from a starless version, but the 'default' usage of the script (using a star mask) worked quite well!.

I also ran the 33 subframes through the NormalizeScaleGradient script, and I think that is my new favorite way of prepping the images just before stacking - the gradients all but disappeared, and I didn't even bother with a DBE this time.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
